Following the lead of its recently facelifted 3 Series siblings, the new model will be offered in three different trim livels: Sport Line, Luxury Line and M-Sport – the latter featuring individual styling touches. It also comes with the choice of two new exterior colours as well as three new wheel designs and what BMW describes as a “wider array of upholstery variants”.
Inside, BMW has moved to answer criticism of below par quality with new trim applications together with lightly altered switchgear, standard Bluetooth smartphone connectivity as well as the latest version of its navigation system. At 520 litres, nominal boot capacity is 40 litres above that of the 3 Series saloon and 25 litres more than that offered by the 3 Series Touring.
The facelifted 3 Series GT will be produced with 18 different engine, gearbox and drive configurations.
As with the facelifted 3 Series saloon and Touring launched in the UK last year, the updated model receives a number of new or upgraded engines, including the latest evolution of the German car maker’s turbocharged 2.0-litre four-cylinder petrol engine, the B48 as it is known internally. It develops 181bhp in the facelifted 320i Gran Turismo and 248bhp in the 330i Gran Turismo.
A further addition to the line-up is the latest incarnation of BMW’s turbocharged 3.0-litre six-cylinder engine, the B48, which provides the new 340i Gran Turismo with 20bhp more than the 335i Gran Turismo it replaces at 321bhp.
On the diesel front, a twin turbocharged version of BMW’s widely used turbocharged 2.0-litre four-cylinder B47 oilburner serves up 220bhp in the new-to-the-range 325d Gran Turismo. It joins four other diesel models in the line-up, including the four-cylinder 148bhp 318d, 187bhp 320d as well as the six-cylinder 254bhp 330d and 309bhp 335d Gran Turismo.
The 320i, 318d and 320d Gran Turismo come as standard with a six-speed manual gearbox, but they can be specified with the eight-speed torque converter automatic that comes as standard on all other models in the line-up and is claimed to provide a three per cent drop in fuel consumption owing to a reduction in converter slip and revised ratios.
Unlike all other facelifted 3 Series Gran Turismo models, which run standard rear-wheel drive, the 335d Gran Turismo xDrive comes exclusively with four-wheel drive. All petrol powered 3 Series Gran Turismo models as well as the 320d and 330d Gran Turismo can be ordered with optional xDrive four-wheel drive.
The most economical model in the line-up is the 318d Gran Turismo, which boasts a claimed 4.5 per cent improvement in economy with combined cycle consumption of 62.8mpg with the standard six-speed manual and 65.7mpg in combination with the optional six-speed automatic gearbox, giving it average CO2 emissions of 117g/km and 112g/km respectively.
The 320d Gran Turismo is claimed to possess an even greater 13.8 per cent improvement in economy with figures of 61.4mpg in manual form and the same 65.7mpg as the 318d Gran Turismo when running the optional automatic gearbox.
Fastest of the lot is the four-wheel drive 335d Gran Turismo xDrive. It sprints to 62mph from standstill in a claimed 4.9sec on the way to a limited top speed of 155mph
Since its launch in 2013, BMW has delivered over 130,000 3 Series GTs worldwide.
